Michael Rozeff says fear is apparent among those with security clearances:
To quote an e-mail:

"That 'climate of fear, caution, distrust, suspicion and persecution' already exists. I have a lot of friends and acquaintances who are what I call ‘clearance concubines’ - in other words, they depend upon their gov’t clearances to ‘earn’ their bread. To a man they are fearful to state or post publicly any criticisms of the recent revelations concerning the Leviathan to whom they are beholden, and it’s pretty funny to watch. On forums and social media, where they have in the past posted numerous political or issue-related comments, they are now strangely silent. Most are professing Christians and ‘conservative’ pro-gun & anti-socialism, even anti-state, but to come down on the side that their natural political bent would place them would jeopardize those clearances, knowing that their colleagues at the NSA will see and record anything they might say. So they cower in their corners."
